YZ450F 08 original pipe

Windseeker

I got my 08 bike today. Surprise - it has a ugly longish wr-style pipe - not the shorty lovingly depicted at the yamaha site. Here are the photos. Has anyone seen this pipe on a 08 bike? Mine is a japanese market version. Thanks.

If I were you, I'd try it the way it is first. That exhaust system will most likely NOT savage your low end power the way the US muffler does. I'm not saying you shouldn't or can't replace it if you want, only that it's probably nowhere near as bad as ours is, and you may like it just fine.

This muffler is used in europe and all other countries with FIM politics because the FIM reduced the sound to 94dB in 2008. It was told that with the US muffler (short version) 94db isn't possible and the AMA has a 96dB limit. So the japanese market is also under the FIM rules.

Ok - promise will break in and ride with this pipe first (normally waiting 3-4 weeks for the staff to arrive from US online shops Then will report on the difference if any (except the noise).

Seems that again grass just seems greener and pipes juicier on the other side ...

I have the same bike with the same pipe, at first I was dissapointed because I like the way it looks the shorty exaust, but It´s just find, or do my friend has a 2007 with a T4 exaust (original header) and it feels a little more powerfull but a LOT more loud, so I like my quiet pipe, at least for now
